A high-resolution 3D exploded view diagram of a science fair bridge model. The model is a cross-section of the Øresund Link. Layer 1 (Base): H-shaped support beams made of grey foam board. Layer 2 (Reinforcement): A grid of bright neon-green balsa wood sticks (representing FRP rebar) suspended inside the next layer. Layer 3 (Concrete): The bridge deck is made of translucent, semi-clear epoxy resin, allowing the green FRP sticks to be seen inside. Layer 4 (Surface): A thin strip of black textured sandpaper on top representing the road. The scene shows the bridge transitioning into an underwater tunnel made of clear resin blocks. Professional lighting, labeled layers, science fair display board in the background, 4k, hyper-realistic hobby materials." See more
